A model  for  the evaluation of real estate regarding the environmental quality can be a tool for the environmental impact studies, relating its effects to the estate values, aiming   at   contributing   to   the   improvement   of   the Environmental  Impact  Studies  and  the  perfection  of  the Environmental Impact Reports, legal devices required by the Brazilian environmental legislation

The methodology was developed after an analytical approach to papers which, having the study of the estate value as central theme, have tried, through a mathematical model, to relate it to the environmental quality of housing. starting from the hypothesis that if one housing happens to have more desirable attributes  -  among them the environmental quality    than another1 this evaluation will be reflected in a higher price in the market. From the methodological profile found in this collection of papers,  a model  for  the evaluation of  the  environmental impact on the prices of the real estate is proposed and, finally, with real estate data extracted from the housing market, this model is tested on a concrete case in the urban structuring of São Paulo City: the Garbage Composting Plant from Vila Leopoldina, with the effects of its environmental impact on the prices of neighbouring residential estates.

It was concluded that judging from the significant  loss, calculated for 33 elements of the research, caused by the disturbance reported as "a bad smell" by the neighbouring population1  it  can be  stated that  on  the whole  of  the physical  space  in  this  area,   the  magnitude  of  the depreciation would recommend the removal of the plant with effective profit not only for the community, but also for the municipality, with a foreseeable increase of the urban and territorial taxes yielded by the restoration of the real estate prices.
